摘要: A method for forming a capacitor includes forming a dielectric layer over a substrate. A conductive layer is formed over the dielectric layer. Dopants are implanted through at least one of the dielectric layer and the conductive layer after forming the dielectric layer so as to form a conductive region under the dielectric layer, wherein the conductive layer is a top electrode of the capacitor and the conductive region is a bottom electrode of the capacitor.
